Description: Welded steel construction means less metal fatigue, allowing for a longer life. The unique base forging method increases resistance to high pressure and gives a degree of durability and performance not found in any other comparable product. Usable in multiple positions: upright, angled, or horizontal. *NOTE: Stroke is reduced by 30% when used in horizontal position. Special grade steel results in high durability and helps to prevent rust. The casting, cylinder, and base are joined by an electric welding method for high strength and leak prevention. The needle valve allows you to control the lowering of the ram. Heat-treated extension screws provide a low pickup height adjustment and maximum lift height.
